国网宁夏电力公司在用电采集系统电压采集功能的基础上,研发出农网电压波形记录分析高级应用功能,实现配变低压出口侧三相电压24小时实时监测预警。供电所运维人员依据电压波形图分析判断,有效排除线路接地、跌落保险熔断、停电检修等引起的短时电压异动情况,效果明显。通过日、月、年电压曲线分析,有效监控“季节性”、“时段性”低电压发生时段及严重程度,针对性综合治理。国网福建省电力公司依托信息系统,科学、精准治理“低
State Grid Ningxia Electric Power Company in the acquisition system voltage acquisition based on the function of rural power grid voltage waveform record analysis and development of advanced applications to achieve distribution of low-voltage outlet side of the three-phase voltage real-time monitoring and warning 24 hours. Power supply operation and maintenance personnel based on the voltage waveform analysis and judgment, effectively exclude the line ground, drop insurance fuse, power outage caused by the maintenance of short-term voltage changes, the effect is obvious. By day, month and year voltage curve analysis, effective monitoring ”seasonal “, ”period “ period and severity of low voltage, targeted comprehensive management. State Grid Fujian Power Company relies on information systems, science, precision control ”low
